"As a game designer, I looked at Beatmania and Guitar Hero. Those games let people be the best cover band they could possibly be. As a musician, I wanted to create a game that lets people express themselves in music, and with Wii Music I think we achieved that."

"We didn't look at the question of whether or not it would appeal to core gamers or casual gamers," Miyamoto said. "It really depends on one's interest in music, not their interest in games. If you're the type of person who taps your feet to a song, I think this will interest you."
"I think you'll find people who are as hardcore playing Wii Music as any other game. I have found that, as a single player, you can spend over three hours arranging a single song. Since there's 50 songs, simple math tells you that you can spend 150 hours playing it - and that's just by yourself.
